Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670812, here are decompositions:

61 + 8670751 = 8670812
103 + 8670709 = 8670812
109 + 8670703 = 8670812
193 + 8670619 = 8670812
223 + 8670589 = 8670812
229 + 8670583 = 8670812
313 + 8670499 = 8670812
331 + 8670481 = 8670812

Showing the first eight; more decompositions exist.
